16 Claims.

The invention of which the following is a detailed description, relates to mechanism for handling articles. Generally speaking our purpose is to provide a unitary machine for continuously stufiing newspapers, that is, assembling the individual newspaper sections in any desired order and delivering the completely assembled newspaper as a unit. To carry out this purpose we provide means to separate a folded section or book of sections of a newspaper or the like from a stack, deposit it upon a moving belt conveyor, in the case of a book unfold each section successively and insert another section. The operations of unfolding and insertion of new sections are repeated as many times as it is necessary to complete the'assembly. In the case of a newspaper this assembly is normally completed Finally the complete newspapers or books are refolded and delivered in an overlapping pile. Such mechanism is particularly useful in conjunction with machines for stufling newspapers such as are disclosed in the copending application of Isidor Tornberg for patent on a rotary stuffing machine, filed February 15, 1940, Serial No. 319,177. ,7 Incidental to the operation of stuffing or insorting one or more sections of a folded newspaper within another unfolded section, it is desirable to arrange mechanism by which the section or sections to be inserted may be withdrawn 3.

from a stack, transferred and placed within the unfolded section. It is an object of our invention to provide efficient means for mechanically withdrawing a flat article such as a folded newspaper section from the bottom of a stack without disturbing the position of the superior sections in the stack.

It is also an object of our invention to effectively grasp the lowermost section or article and transfer'it rapidly and compactly to a delivery point from which it will be released to fall as in- 1 tended in. place for subsequent assembly with other like sections.

. A further object of our invention is to provide means for positively engaging an edge of the section to be inserted and peeling it from the section when the latter has been unfolded. The inserted article may consist of one or more similar folded sections of a newspaper. In carrying out these objects folded newspaper sections must be fed individually from the open base of hoppers. If the individual sections are the ones which will ultimately be the outer sections of the assembled newspaper, these sections as fed must be delivered in place upon a conveying means and opened up to receive inserted sections. -Our invention is applicable to feeding the sections whether they are toform the outer enclosingsections or merely the inserted inner sections. The operation starts with engaging the folded edge of the lowermost section of a stack and peeling that section from the stack without dragging the next adjacent section out of its position or imposing any frictional pull upon it. I

The engaging operation is followed by rolling or coiling the section compactly during its transfer to a selected delivery station. At the latter position the engagement is broken allowing the transferred section to fall into place upon the conveyor or the like where it will either form an enclosing section oran inserted section with- 'in such enclosing section.

The action of separating the section from the stack may be termed that of peeling in that We' use a rotary roll having means either pneumatic or mechanical for grasping the folded or leading edge of the section and thereafter moving in an orbit or circular path. By the continued rotation of the roll the section is transferred to the point of delivery at another point in the orbit of the roll. Finally on arrival at the delivery point, the holding or gripping means is automatically released and-the section falls by gravity with its folded edgeleading to the place where it is received for opening or placement within a sec.- tion already delivered and opened.

Incidental to the withdrawal of the lowermost section from the stack, means are providedlfor supporting the next lowermost or superior section in place without unnecessary frictional-drag or dislocation so that it will .be in position to be gripped in its turn.

A further object of our invention is to prepare the section as delivered to the moving work surface anddirecting its travel thereover, for receiving one or more inserted sections. In carrying out this purpose the initial section isunfolded to receive a second inserted section. In the case of a bookthe unfolding operation is repeated for each section in the book prior to F the. insertion of the new section.

foundation frame I relatively long and supporting an endless conveyor 2. At one end the conveyor passes beneath a feeding unit 3 by. which folded sectionsof a newspaper are successively peeled, from the bottom of a stack and deposited upon; a work surface in the form of a trough 4 that extends lengthwise of themachinethe foldednewspaper section is carried along it passes through an opener 5' in which the section is unfolded or in the case of a. book each section isesuccessively unfolded by separate opening devices 6, I and'8.

The unfolded section or group, of sections. in

the, case of abook, then travel beneath a second feeding'nnit 9 where. a further inserted section is deposited within the unfolded section or book. The opening operation may then be repeated on the innermost section and a third feeding unit mayadd another insert. These operations are repeated in they above. cycle as many times as'is found necessary or, desirable.

At the end of the conveyor travel the unfolded sections with the inserts. are pushed along the troughover an endless belt conveyor m, and at the same time folding means l l .closes. the opened sections of the assembled newspaper. This is Fig. 17 is a side elevation of the closing unit Generally speaking the machine comprises a.

followed by the operation of a lifter and pusher I2 which will liftthe paper out of the trough, push it a considerable distance away from the trough and deposit it on the delivery conveyor.

The feeding unit is supported on any suitable cross bars or beams l3, l3 and is located generally above the stuffing. conveyor.

Mounted upon beams l3, l3 are two frame members It and I5. The upper portions IS, IS curve inward toward each other parallel to the general longitudinal axis of the machine. A shelf l8 having an open bottom bridges the space between the ends l6, l6. This shelf slopes as indicated in. Fig. 3 and supports the hopper l8 having an open, bottom. The hopper is proportioned to. receive a stack of folded newspaper sections which will lie flat across the bottom of the hopper. The stack of sections rests with the lowermost having its leading folded edge against the back of the hopper while the opposite free edge rests directly on a ledge 20. The ledge serves to support the stack at this point subject to the tilting movement of the lowermost section. As the leading or'folded edge of the lowermost section falls downwardly, the opposite free edge escapes from the ledge 20 and rests upon aroll 2|. The-back wall of thehopper l9 carries a plate 22 which extends substantially the full length of the wall of the hopper. The upper portion of the plate 22 is of limited length as shown in Fig. 3 and held in an adjusted position by the bolts'23.

The lower edge of the plate 22 has an inturned lip 24 shown in Fig. 3. This serves as a rest for the leading folded edge of the bottom section.

The back of the hopper I9 carries a pair of brackets 25-. Journall'ed in these brackets, is a rotaryshaft 26- carrying a pulley 21' receiving power from the belt- 28.

Suitably spaced along the shaft 26 are circular brushes 29', 29. These brushes are of sumcient length to extend through slots 30, 30 in the back of the hopper I9. The shaft 26 is arranged to rotate relatively slowly and the brushes serve to engage the folded edge'of the lower sections of the stack and bring them down so that the lowermost is in position to be engaged by the gripping roller and the next section temporarily rests upon the lip 2 4'while the others are in position to replace the lowermost section in that position as the latter in turn is removed.

The rotaryshaft 3| is journalled in bearings 32 32 in the frame members l4 and IS. The shaft 3| is connected to adjacent shaft sections 33 at one or both ends by means of couplings 34. In this manner shaft 3| may receive power from shaft 33 or under certain circumstances shaft 3l'nay transmit power to anadjacent feeding um As shown in Fig. 2 the frame l4 carries a stationary bracket35 capable of rocking adjustment around the lock nut 36 as indicated in dotted lines on Fig.3. Thi s bracket 35 is connected" to the vacuum line 31 and contains a passageway 38. Forming part of the bracket 35 is the stationary sleeve 39. This sleeve surrounds the; rotary shaft 3| andforms an extension of one bearing 32. The sleeve is recessed to form a chamber 40.

This. chamber extends half. around. the sleeve with shaft 3|. This gear forms. an internaltrack along which pinions travel in an orbit and trans- 'this' latter instance four vacuum rolls are dismit rotary motion to the operative parts of the gripping and transferring element as well as to the means for supporting the sections in the stack. I

Spiders 42, 43 are carried on shaft 3| and form the ends of an open drum. The parts of the spider are cut away on opposite sides to form recesses for the devices which engage the articles to be transferred. These recesses are bounded on the inside by curved guards 44 (Fig. 3). The spiders carry bearing plates 45 extending radially outside of the spiders 42 and 43. Centrally of the bearing plates are the journal bearings 46. Bracket plates 45 on spider 42 have manifolds 41 covering the ends of the bearings 46. These manifolds connect with the opposite sides of a collar 48. This collar rotates with the yoke 42 around stationarysleeve 39 as a journal'bearing. On the inner surface of the collar 48 the manifolds 41 have inlet ports 49. These ports are relatively narrow in a circumferential direction but relatively long in the direction of the axis of shaft 3|. This design is selected in order that connection of the ports 49 to the vacuum chamber 36 shall be accomplished in a minimum angular travel but without diminishing the cross" sectional area of the 'portto be evacuated. Thus the vacuum is applied through the manifold 41 in the shortest possible time and with the greatest effectiveness.

The bearings 46 carry the hollow shaft which forms part of the gripping cylinder 5|. One end of the hollow shaft is closed but the other one passes through the bearing 46 and is in communication with the manifold 41. g

The closed end of the shaft carries a pinion 52 which is in engagement with the ring gear 4 The pinion 52 has a pitch diameter one-fourth that of the ring gear 4| so that the shaft 58 rotates four times during its orbital travel around the ring 4 I. g

The hollow shaft 56 has a series of radial passageways 52 which form a line of openings longitudinally of cylinder 5| as shown by dotted lines in Fig. 5. These openings apply vacuum transmitted through the hollow shaft 50 and the manifold 41 when the shaft 3|, spider 42 and appropriate manifold 41 pass over the open vacuum chamber 36 in the stationary sleeve 39. The operation of the vacuum ports 52 is interrupted by lifting fingers which break the vacuum. In Figs. 5 and 6 we have shown these devices to be fin-. gers 53 which rest normally within peripheral channels 54 of the cylinder 5|. These fingers are attached to a rock shaft 55 journalled in opposite ends of the cylinder 5| and lying parallel to shaft 56. Shaft 55 carries a bell crank lever 56, one end of which is held inwardly by means of a plunger and spring 51. The opposite end 58 of the lever has a slotted connection with an end 59 of a second lever 60. Lever 66 is carried upon a stud 6| on the end of cylinder 5|. The free end of the rock lever 59 carries a stud 62 and a roller 63. Roller 63, in its normal travel contacts stop 64 on the frame beam l3. As roller 63 rides over stop 64 the leverage compresses spring 51 and permits fingers 53 to move outwardly from cylinder 5|. This pushes the paper section away from the vacuum outlets and causes it to drop to the trough below.

Figures 2 and 3 show two vacuum rolls mounted diametrically. Figure 1 shows how rolls may be disposed in such fashion as to transfer successive sections to alternate conveyors 65, 66. In

posed at equal distances around the main cylinder. I

The main cylinder or drum is provided with guard belts 61, 61. These belts areof any desired number equally spaced longitudinally of the device. Their purpose is to'prevent a section from the stack from falling into the cylinder during and subsequent to the peeling of the lowermost section from the stack.

For this purpose the spiders 42, 43 carry two series of rolls 68. Each series of rolls'is of any v suitable number and indicated in Fig. 3 as 680 68h. These rolls are arranged tangential to the drum ends 42. The left end of each drum as shown in Fig. 2 revolves around the pin 69 which is held within the fixed bushing 19 on the spider 42. The pin 69 rna'y be removed from the bushing 16 in order to permit removal'of the individual rolls. At the opposite end each roll has a shaft 1| extending through removable bushings 12 in the spidei43. At the end of'the shaft 1| there is the pinion 13 in mesh with the fixed ring gear 4|. By removing the pin 69 andthe bushing 12, the pinion 13 is disengaged from the ring gear 4| and the roll may then be removed.

In order to adjust the spacing of the bands 61 from-the vacuum rolls 5|, additional rolls 14 are mounted at opposite ends of the series of rolls Gila-68h. Ro1ls 14 are mounted in bearings 15 on arms 16. Arms-16 are mounted on plates 45 at the pivots 11 and the arms have intermediate slots 18 permitting adjustment around studs 19.

On spider 43 the arms 86 are pivoted at an intermediate point 8| and move around an adjustment 82 atfltheinner end opposite the bearing for the roll 14. In this way the roll 14 may be adjusted to and from the vacuum rolls 5| and when the latter areto be'removed the "arm 16 may be swung out to afford clearance for the removal of the drums 5|. I

The bands 61 travel through grooves 83 in the rolls 68 and 14. Within the periphery of'the drum, the bands 61 return around idlepulleys 84' carried in bearings 85. The reason for running the hands over rolls 84 is that the surface movement of the rolls is opposite to the direction of movement of the paper around the adjacent vacuum roll. If not pulled out of the way the bands would interfere with thepaper section and might pull it free from the suction.

The prime object of the bands of course is to prevent the lowermost section from dropping except when engagedby the vacuum rolls. ,The rolls 68 and bands 61 may be considered as a moving retainer for the stack free from friction.

On Fig. 3 has been shown a guard 86 which serves to hold the free edge of the coiled paper from flying away from the vacuum roll so that the paper section is constrained to travel around with the vacuum roll until released from the vacuum by the lifting fingers and dropped to the receiving trough.

On Fig. 8 we have shown a modified form of vacuum roll 6|. In this instancevacuum is exerted through the hollow shaft 50 while the opposite end 81 of the shaft is connected to a I source of pneumatic pressure in the same manner as shown in Figs. 2 and 3 for vacuum. The vacuum passage extends radially'as at 88 to a manifold 89 which is connected to ports 96 uniformly distributed in pairs along the length of the vacuum roll.

-- Intermediate each pair of vacuum ports 99 is passageway 93 whicheinaturn connects withthe central passageway 94 running through theend 91 ofithe 'shaft and connectedwiththe source of": ainpressure- :arrangement substitutes-pompressed 7 air I for; themechanical.motion-of the lifting fingers inreleasing the -sheets from the vacuumroll. As I the vacuum roll rotates theconnectionwith the vacuum is broken and simultaneously. .connec- -tion established with a source of air pressure causingthe paper to be; released from" theroll at the proper time. In Fig. 12 we; have showncurvedspring fingers 95' journalled'on-v a: shaft' in the vacuumroll 5h An arm 96 has aroller 91 at its free-end which contacts with'a fixed cam 98;

Each pusherr bar engages the unfoldedside edge of the paper-section I I8. As indicatedinFig. 14. this papersection rests upon itsintermediate folded: edge in the base of the trough- 4.

Idlers I I9 support the upper flight of the chains I I=5 'at suitable spaced intervals.

By the above arrangementrthe endlessconveyor 2 -travels continuouslyto advance the paper sections along the. lengthofthe trough 4 and from 'whichever position they, are deposited by the feeding units 3-017 9;

; The. first, feeding; unit drops the. outside paper called the coversection... This. section maybe made. up of.one,:two:or-three sections which are folded. togetherwith ai-h alf-page fold.. In the case of several sections it"is necessaryto' open all ofwthese before any-inserts. can be dropped in. For. this reason.- it is. necessary that some mechanism be provided that will' open the cover sectionfbefore it reaches the first inserting-unit. Guides, must also be. provided to: keep the unfolded sections from closing until. they have .passed thelastinserting' unit. This mechanism vis the-opener unit andcis located between the depositing unit 3*- and successive inserting I units 9. We havepro vided an. opener unit which will be automatic;to-the. extent that at= no-time will it benecessary-to make-anychanges or adjustments regardless of. whether the cover section consists 0t one,:two or. three folded sections. or

There maybe, several such units. each. feeding aninse'rt section and the number of units will beliinited only by the required number of inserts.

The 'fihal assembled newspaper or book will then pass on to thedelivery unit which will close or refoldthe cover section on theinserts and. deliver thestufiedpapers. The opener section 5? receives power from the cylinder shaft 3] by' the sprocketl'Ilf, chain IIZ, sprocket H3 neath a short vertical shaft I2I which is journalled in the side of frame I and has a corresponding miter gear I22. The upper end of shaft I2I carries a bevel gear I23. A crossframe I24 of the frame carries a stud shaft I25. This shaft has an idler comprising a lower bevel gear I26 and an upper spur gear I21. Gear I26 meshes with gear I23.

A pair of opener shafts I28, I29 are journalled in the cross-frame I24 at inclinations to the vertical as shown in Fig. 14. Shaft I23 carries a spur gear I30 in mesh with gear I21. A similar spur gear I3I is keyed likewise to shaft The cross-frame I24 has two stud shafts I32 and I33 intermediate the shafts I28 and I29. Each stud shaft carries a combined bevel and spur gear I34 similar to the gears I26 and I21. Gears I26, I21, I28, I34 and I3I constitute a train by which gear I23 rotates both shafts I28 in opposite directions and at speeds identical with that of shafts H and I2I.

The shafts I28 rotate within bushings I35 as shown in Fig. 14. The shafts have axial passageways I36 into the hollow cones I31. The cones have slotted openings I38 arranged to meet face to face during the rotation of shafts I28, I29. The cones are spaced approximately one-quarter of an inch apart at their nearest points although this spacing may be varied in accordance with requirements.

Shafts I28 and I29 each have radial bores I39 which register with similar openings I40 in the bushings I35.

Bushings I35 may be adjusted radially and thus vary the timing of the registry of bores I39 and openings I40.

Surrounding the mid-portion of the bearings containing the bushings I35 there is a cored passageway I4I. These passageways are connected as indicated on dotted lines in Fig. 14 and one of them extends as indicated in I42 to connect with a vacuum line I43. In this way Vacuum is applied through the slotted openings I38 during part of the rotation of the cones I31, dependent upon registration between the bores I39 and the openings I40.

Fig. 16 shows graphically the arrangement of the opening units and their operation. The trough 4 carries a pair of centering guides I44 in advance of the first opening device 6. These guides form a throat which brings the paper section II8 into the space between the cones I31, I31 due to the forward movement of the push rods II1.

Between the opening devices 6 and 1 and also between the opening units 1 and 8 means are provided for spreading the leaves engaged by the cones I31, I31 and at the same time centering those folded leaves which are inside the outer ones engaged. Thus the spreading guides I45 diverge from a point near the preceding opening device and extend beyond the cones of the succeeding opening device so that the outer folded sheet engaged by the preceding cones will be directed outside and around the succeeding separating cones. p

Joining the front edges ofthe spreading guides I45 are centering guides I46 which constitute a throat feeding the inner section or sections of the paper between the' succeeding opening device.

Beyond the last opening device 8 a pair of divergent spreaders' I41 guide the separated portions of the innermost folded leaf in opposite directions and toward the outer sides of the trough. Assuming three folded sections to be fed, the opening device 6 will divert the outer or cover section to the sides of the trough thus opening this section. At the same time the center section and innermost section not being affected by the opening device 6 will be directed between the cones of the opening device 1. Here the; center section will be unfolded and its portions spread out so as to join the cover section resting on the sides of the trough while the innermost section will be advanced between the cones of theopening device 8. The separation of the innermost section then takes place and its portions spread to lie adjacent the other sections on the sides of the trough.

It will be of course evident that if the section fed has only two folded portions the operation will be completed by the opening device 1 and the opening device 8 will be idle. In like manner if the paper section 8' is a single folded unit then both opening devices 1 and 8 will be idle. 7

Leaving the-area of the opening device 5, the section'fed by the unit 3 has now been separated or unfolded. As it is pushed beneath the succeeding feeder 9, a section to be inserted is dropped within the opened section I I8.

If a third section is to be inserted in the already assembled material, a second opening unit 5 will follow the feeder 9 and this in turn will be followed by another feeder 9.

After the cover sheets or first sections have been opened and have passed out of the opener units all such sheets are kept open by guides parallel to the sides of the trough until all inserts have been dropped into this cover sheet. The guides will then present the completed book for closing and delivery.

The closing and delivering unit is shown at the extreme right of Fig. 1 associated with the folding means II.

The foundation or frame I is extended beyond the length of conveyor 2 to provide a support or a frame I48. Journalled in this frame I48 is a v shaft having at one end a bevel gear I50 in mesh. with gear I5I on the sprocket'wheel II6.

At the opposite end of the frame shaft I49 projectsto carry a keyed sprocket wheel I52. Across the top of the frame I48 extends a fan shaft I53. This has a sprocket I54 driven by sprocket wheel I52 through chain I55.

As illustrated in Fig. 18 shaft I53 has outwardly extending fan fingers I56. These are three in number. i

An inclined wall I51 extends across the frame and forms a continuation of trough 4 and side pieces I06. Wall I51 is slotted as shown in Fig. 17 to permit the rotation of the fan fingers I58. The bottom edge of wall I51 has a concave hollow foot I58 which forms a continuation of the bot tom of trough 4. Foot I58 is also slotted as shown in I59.

Across the end of wall I51 extends an adjustable stop I60 suitably mountedon bars l6l in the frame I48. 7

A worm gear I62 is keyed to shaft I49 and engages a large gear I63 keyed on a short shaft I64 which extends inwardly of the frame. At its other end shaft I64 has a bevel gear I65. This is part of a shaft I66 extending lengthwise of the frame. Suitably spaced along shaft I66 are pulley wheels I61. Between pairs of pulley wheels I61 is arranged an eccentric wrist pin I68. These wrist pins form bearings for rock arms 6 asses-co IE9. The upper-portions of the rock arms form stirrups I10 which in one position are continu ations' of the concave foot 158.

Extending downwardly f-rom the rockar-ms l69-a-re pins l1l. These'are loosely iournalledin holes transverselyof therockshaf-t I12.

As shown in Fig. 1-8 a pedestal I13 is'firounted .--'I-his beyond the opposite side of the frame 1' pedestal carries" a shaft 1 14 having a roller 11 5. A series of belts 1'16 extend over-the pulley wheels H31 and'the roller l15.- A series of tensioning idler-s I11 are mounted on a rock arm I18 of pedestal I13. 1

Beneath the frame 148 and at the right of Fig. 1'7 will be seen a-tensioningrock arm -I1 9-. This carries a stud shaf-t I80 which forms a bearing for a sprocket wheel l8l. Chain I54 is brought around an idler I82 and then around the tensioning sprocket IBI. 7

To summarize the-operationof the machine,it

will be evident that a single rotation of shaft 3| will deliver two cover sections from-the feeder cylinder 3. Eachcover-section falls with its halfpag fold at the bottomof trough "4 in advance of one push bar [11. Ihe chain drive 1-H advances to push bars H1 at an appropriate speed. Each coversection H8 as it approaches the opening unit 5-is unfolded oropened in a manner illustrated in Fig. 1-6; As-stated' above the unfolding operation is applied to each folded part of section H8. 2

The completely unfolded section is held out toward the side walls of the trough 4 and side pieces I05 by spreaders M1.

Immediately following the openingunit 5 the section comes beneath the inserting unit 9. This is similar to the feeding section '3. Here the folded section is inserted within the unfolded or opened cover section.

Beyond the inserting unit 9 the lastinserted section may be unfolded or opened by -a second opening unit similar to 5.

After all insertions have been made the ma- .terial is projected upon the foot +58; forming part of the closing anddeliveryunit. This'foot is a continuation of one side ofthe trough 4 and one-side piece 196. -A suitable converging guide may direct the oppositeside of the opened sections toward the wall 151.

The push bars H1 drop down and return tc the opposite end of the machine.

The folding and delivery unit is operated in timed sequence from sprocket wheel H6. in successive order, the concave foot l-58 is-given a compound oscillation raising the fold of-thecover section H8; moving laterally to "drop -iton the conveyor bands I16 at a point out of line with the trough 4.

Simultaneously the fingers 156' have thrown the upper free edges of'the section I I8 over upon the conveyor bands 116 or more properlyupon the preceding paper section already deposited there.

Thus the successive sections aredropped in an overlapping pile upon the moving bands I16 and the concave foot I58 is ready to receive another paper section H8.

'The' shaft I53 rotates atone-third rtne speed,

of the shaft 1%.
